Dispensing container

ABSTRACT

This invention relates to a reinforced disposable container which comprises a cylinder of paper, plastic, metal, canvas or plastic-coated metal sheet with panels at opposite ends, the panel at one end having an opening with closure means. A fabric reinforcement surrounds at least a part of the cylinder and the panel at the one end with an opening therein coextensive with the opening in the panel to permit removal of the closure and dispensing of the contents in the container.

In the prior art, it has been necessary to send back a container for transporting a powder or the like after it is transported to a destination which adds to the cost of transporting the powder.

Further, such containers are heavy and difiicult to handle and frequently break while the powder or the like is being transported adding to the expense.

An object of the present invention is to provide a container which is disposable and which is made in the form of a cylinder composed of paper, plastic, metal, canvas or plasticcoated metal sheet panels, panels being provided at the opposite ends of the cylinder. An opening is provided in one of the panels with a closure for the opening. Fabric reinforcement surrounds at least a portion of the cylinder and the one panel, an opening coextensive with the opening in the panel being provided in the fabric reinforcement.

In the drawings:

FIG. 1 is a plan view of a container according to the present invention;

FIG. 2 is a bottom view of FIG. 1;

FIG. 3 is a perspective view showing only the cylinder of the container of the present invention;

FIG. 4 is a partly sectioned side view of the container according to the present invention.

A cylinder 1 is formed by properly rolling a paper, plastic, metal, canvas or plastic-coated metal sheet and stitching or welding it at both ends (See FIG. 3). A bottom plate 3 made of the same material as the cylinder and provided with a central aperture 2 stitched or welded on the outer periphery to the bottom of said cylinder. Further, a cardboard 5 having perforations 4 forming a circle is fixed below said bottom plate 3. The diameter of said circular perforations 4 is made substantially equal to that of the central aperture 2. The perforations 4 and central aperture 2 are aligned with each other. A tab 7 is fixed to circular part 6 formed within said perforations 4. A reinforcing bag 9 made of canvas and having an aperture 8 in the bottom is applied to the lower part of the cylinder 1. Belts 10 are properly fitted to the upper side of said reinforcing bag 9 so as to be convenient in hanging up the container. The

cylinder 1 is covered at the top with a proper lid 11.

In the present invention, the lid 11 is applied after such contents as a powder or the like are put in from above. When the contents are to be discharged, the tab 7 in the bottom is strongly pulled and the circular part 6 is peeled off at the perforations 4 and the contents are dropped and discharged through the central aperture 2 of the bottom plate 3 of the cylinder 1 and the apertures in the cardboard 5 and bag 9.

Thus, according to the present invention, a container which is disposable after being used can be made very cheaply and discharge of the contents is simple.

Further, as such container is disposable after being used, it is not required to be repaired or sent back. Therefore, such expenses can be saved.

What is claimed is l. A reinforced disposable container comprising:

a. a cylindrical wall,

b. wall means at opposite ends of said cylindrical wall,

c. the wall means at one end comprising an annular member secured at its periphery to said cylindrical wall, a panel secured to said annular member and having a plurality of perforations therein forming an annular configuration defining a removable portion of said panel, and

d. a flexible web reinforcing means surrounding at least a part of said cylindrical wall and the wall means at said one end, said reinforcing means including a circular aperture having a smaller diameter than the diameter of said removable portion of said panel, V

e. whereby said removable portion of said panel may be torn along said perforations forming a further aperture in said panel and removed through said aperture in said flexible web reinforcing means and the contents of the container can be dispensed through said aperture in said panel and flexible web reinforcing means.

2. A container as defined in claim 1 further comprising belt means secured to said web reinforcing means for suspending the container with said one end oriented downwardly.

3. A container as defined in claim 1 wherein said wall means at the opposite end of said cylindrical wall comprises a lid. 

1. A reinforced disposable container comprising: a. a cylindrical wall, b. wall means at opposite ends of said cylindrical wall, c. the wall means at one end comprising an annular member secured at its periphery to said cylindrical wall, a panel secured to said annular member and having a plurality of perforations therein forming an annular configuration defining a removable portion of said panel, and d. a flexible web reinforcing means surrounding at least a part of said cylindrical wall and the wall means at said one end, said reinforcing means including a circular aperture having a smaller diameter than the diameter of said removable portion of said panel, e. whereby said removable portion of said panel may be torn along said perforations forming a further aperture in said panel and removed through said aperture in said flexible web reinforcing means and the contents of the container can be dispensed through said aperture in said panel and flexible web reinforcing means.
 2. A container as defined in claim 1 further comprising belt means secured to said web reinforcing means for suspending the container with said one end oriented downwardly.
 3. A container as defined in claim 1 wherein said wall means at the opposite end of said cylindrical wall comprises a lid.
